CIRCUIT BREAKERS FOR EQUIPMENT

The TM12 circuit breaker for equipment (CBE) is a single pole, ther-

mal-magnetically operated device providing small size, low cost and

reliable trip-free operation on overloads and short circuits within the

maximum breaking capacity. It is intended primarily for the protection

of circuit control functions in sensitive instruments etc. It is not

generally suitable for line protection unless the prospective short cir-

cuit current is less than 200 A at 240 V a.c. (400 A at 28 V d.c.).

TM12 Series

• Thermal magnetic release

• Positively trip-free

• Reset or manual

actuation

Threaded neck and flange mounting types are available each with

optional push on/push off mechanism, shunt terminal and auxiliary

contact. There is also a choice of screw clamp terminals on certain

types.

The well proven mechanism is designed to open the contacts in the

event of overloads. A bimetal strip is heated by the overcurrent and

deflects, thereby releasing the latch mechanism. If the overcurrent is

sufficiently high, the magnetic release will operate and open the

circuit instantaneously. Two characteristics are available. The more

commonly used T characteristic has operating limits between 8-12

times the rated current. The optional F characteristic operates at a

lower current levels of 4-8 times the rated current.

In case of overloads, the contacts will open even if the reset button is

manually held in the closed position. This is known as a trip-free

feature. The contacts open and close with a snap action and the

tripped state is clearly shown by the increased projection of the reset

button. After the opening operation, the reset button has to be fully

depressed, then released, to effect a closing of the contact.

It is impossible to «tease» the contacts by gentle pressure on the

reset button.

Available options

• Fast and slow magnetic tripping characteristics

• Flange type

• Threaded neck type

• Type of actuation: reset or manual ON/OFF (push/push)

• Terminals: quick connect or screw clamp terminals

• Independent auxiliary contact (change-over contact)

• Shunt terminal

• Setting indication on reset button indicates the position

of the contacts

Special features

• Competitive pricing

• Quick connect terminals

• Choice of mounting styles

• Positively trip-free

• Insensitive to shock or vibration

• UL, CSA, VDE and other approvals
